GLASS JAR FOR FlRE-EXTlNGUlSHING COMPOUNDS AND OTHER SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 314,885, dated March 31, 1885.

Application filed March 2, 1885. (N0 model.)

To all whom, it may concern.-

Be it known that I, JAMES B. SMITH, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Glass Jars to Contain Fire-Extinguishing Compounds or other Substances; and I do hereby declare that the following is a true and exact description thereof.

My invention is intended to cover a vessel for holding fire-extinguishing liquid, and has special reference to its stopple or cover; and it consists of a stopple of peculiar weight and construction, so that it can be easily and speedily broken inwardly by a single rap, without injury to the other parts of the jar or obstruction to the outflow of the liquid; and,

" secondly, in a new and useful construction for fastening and sealing such a stopple in place, consisting of an annular chamber around the periphery of the stopple, into which is placed an adhesive substance, in combination with the shoulder or shelf upon which the stoppe rests, which forms a new, secure, and conveni ent fastening for such purposes.

Vessels for holding or transporting chemicals or liquids to be used in extinguishing fires have been made of different kinds of material, of glass or metal, or equivalent substances. Such vessels have been used with stopples or tops made of cork, rubber, lead, wood, and glass; but when the chemicals come into contact with the cork, rubber, wood, metal, or similar substances corrosion takes place, and in time destroys the stopple. In all previous vessels for such purposes the vessel it self had to be broken or delays occur in removing the stopple in order to relieve the chemical liquid for contact with the fire.

In the drawings, Figure l represents my invention when put together. Fig. 2 is a vertical section of the same, showing its parts.

Ais the vessel, preferably of glass, and made of any convenient size. D is a disk made of glass or some frangible material, of such a weight and thickness with reference to the shoulder or shelf upon which it rests and with reference to the walls of the jar as that by a quick rap the stopple will be broken in pieces without injury to the other parts of the jar. This disk is preferably provided with a handle or knob, K, either molded with the disk or made separate, of any suitable material, and afterward attached thereto by some suitable cement or wax.

The glass vessel or jar is made with a circular flange, F, provided with an annular rim, R, raised above the mouth of the vessel.

Vhen the vessel is filled with the liquid designed to be used to extinguish fire, the disk D is placed on the flange within the rim R, and is then cemented by pouring the cement or wax into the annular chamber around the edge of the disk, so as to prevent the contents of the vessel from escaping.

When the contents of the vessel are to be used, by reason of the stopple or top being light and frangible, it can be easily broken by a slight blow with the hand or any knocker upon the knob K, thusliberating the contents, which can be thrown or dashed into the fire.

WVhat I claim, and desire to be secured to me by Letters Patent, is-

A jar provided with a stopple of glass or other frangible material resting upon an annular shoulder in the neck of said jar, which shoulder terminates in an annular cavity forthe reception of the sealing substance, the said stopple being of lighter construction than the shoulder upon which it rests, substantially as and for the purpose set forth.
